I write an essay every day, but I'm not sure my Engsish is correct or not.
Could you check it and please let me know if there are any mistakes?
Thank you.

The hardest goodbye I ever had is in Cambodia. Three years ago, I went to Cambodia to teach Engsih and Japanese. It was my first time visiting other countries alone, so I was worried about everything like the fight and the life there. Actually, the life in there was totally different compared to Japan. I did Homestay, so I stayed at the resident's house. It didn't have any electric equipments and faucets. When I washed clothes, I had to use well water. I couldn't believe the situation because I never used well water in Japan. It was a little bit hard to live there. However, the residents were very kind and friendly, even though I was a stranger. I didn't understand the language spoken in Cambodia, but they accepted me. I learned that the languages didn't matter to connect people from other countries. The best thing was heart. When I had to say goodbye, every memory I experienced there was flashbacks, then I didn't want to leave. It has been a while since I visited there. When I have time. I would like to go there to meet them.
